Hello Nahiro,

Which version of this toolkit you're using? You get from itch.io or Unity Asset Store? 

Thanks for the question and for purchasing the toolkit! I double‑checked the docs.

The “wind effects” mentioned in the docs are implemented, but only for Terrain grass details (the built‑in grass / billboard details). Those use the G5WavingGrass shaders, which include a procedural wind/wave animation. Detail meshes (painted as meshes) use a different shader (G5TerrainDetail), and that shader doesn’t include any sway logic — so there’s no place to “enable” it right now.

You’re absolutely right that the docs don’t clarify where the effect applies; I’ll update the documentation to make it explicit that it applies to Terrain grass details, not mesh details.

If you’d like, I can implement sway in the mesh detail shader as well (so painted meshes move similarly). Just let me know and I can add it as a request.

Hi! Just a quick update 😊

I’ve released a new update both on itch.io and the Asset Store, adding the wind effect directly to the G5Lit shader. You can find it in the Advanced Options of the default pipeline material (G5Lit):

• If you enable the Wind override, the shader will use the advanced sliders to control the wind effect directly.

• If you disable it, the material will automatically use the wind settings from the Terrain instead.

This gives you full control, depending on whether you want per-material customization or global terrain-driven wind. Let me know if you have any questions or feedback — happy to help! 🙌

Just a heads up, the Asset Store can take 1 to 3 days to approve the update, but if you want to test and use it, you can use the version available here on Itch, it's version v2.0.2.
